Objectives: The code for the different stack and queue operations in both implementations (array and linked list) are discussed in the lectures: and are written in the lectures power point. So the main object of this assignment is to give the student more practice to increase their understanding of the different implementation of these operations. - The students also are asked to write by themselves the main methods in the different exercises below; The Lab procedures: The following files must be distributed to the students in the Lab - arrayImpOfStack.java // it represents an array implementation of the stack. - pointerImOfStack.java // it represents a Linked List implementation of the stack. - pointerImOfQueue.java // it represents a pointer implementation of the queue. Then the students by themselves are required to write the code for the following questions Ex1) Given the file arrayImpOfStack.java then write a main method to read a sequence of numbers and using the stack…
Help please the function isFull is the only one I need help with it is supposed to return true if the array is full and false if it is not full I Just need to know the code to check if it is full or not help please this is from the study guideC++
Quick Sort We choose an element from the list, called the pivot. We'll use it to divide the list into two sub-lists. We reorder all the elements around the pivot The ones with smaller value are placed before it All the elements greater than the pivot after it. After this step, the pivot is in its final position. This is the important partition step. We apply the above steps recursively to both sub-lists on the left and right of the pivot. Quick Sort (Example) Consider the following array Arr[] = {5, 9, 4, 6, 5, 3} Let's suppose we pick 5 as the pivot for simplicity We'll first put all elements less than 5 in the first position of the array: {3, 4, 5, 6, 5, 9} We'll then repeat it for the left sub-array {3,4}, taking 3 as the pivot There are no elements less than 3 We apply quicksort on the sub-array in the right of the pivot, i.e. {4} This sub-array consists of only one sorted element We continue with the right part of the original array, {6, 5, 9} until we get the final ordered…
How to answer the following questions screen shot show the text's arrayboundedqueue and the array unbounded queue The text's array-based queue is being used and holds a queue with a single element. We can say: A. the element is held at index 0. B. the value of front is -1 C. the value of front is one less than the value of rear. D. the value of front is equal to the value of rear.
You will create two programs. The first one will use the data structure Stack and the other program will use the data structure Queue. Keep in mind that you should already know from your video and free textbook that Java uses a LinkedList integration for Queue. Stack Program Create a deck of cards using an array (Array size 15). Each card is an object. So you will have to create a Card class that has a value (1 - 10, Jack, Queen, King, Ace) and suit (clubs, diamonds, heart, spade). You will create a stack and randomly pick a card from the deck to put be pushed onto the stack. You will repeat this 5 times. Then you will take cards off the top of the stack (pop) and reveal the values of the cards in the output. As a challenge, you may have the user guess the value and suit of the card at the bottom of the stack. Queue Program There is a new concert coming to town. This concert is popular and has a long line. The line uses the data structure Queue. The people in the line are objects…
Can anyone please solve this question asap ? Thank yoyuIn this question, you are required to implement singly linked list and its concepts to solve the problems of a departmental store described in the scenario given below:A departmental store has a variety of products to sell. Each product type has a unique ID and price associated with it (for example soaps can have an ID of 1 and price of 50 etc.). A customer comes to the store and starts putting items in his/her shopping cart. Once all theitems have been placed in the shopping cart, the customer then proceeds to checkout but before that, he/she will sort (in ascending order of IDs) the shopping cart’s items and proceed to remove all the duplicate items from the shopping cart, that is if two soaps have been added to the cart, only 1 will be kept. At the checkout counter, he/she will then remove items from the cart by removing from the end of the shopping cart (linked list). A bill for that customer is then generated and printed.You…
Below are some statements about Quicksort and Heapsort. Which of the statements is correct when sorting a large number of elements? A. Heapsort and Quicksort have the same time complexity in the mean case.B. When implementing Quicksort, an extra array is usually used in addition to the one on which the sorting is performed.C. If the first element is selected as the pivot element at Quicksort, Quicksort will be faster than Heapsort when the sequence to be sorted is already almost sorted.D. Heapsort performs the sorting on linear time at its best. Group of answer options All statements except B are correct Only statements A and C are correct Only statement A is correct All statements except D are correct All statements are correct
